Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

Biology Animal Phylums "Write a three sentence description for each phylum and list two examples for each. Also‚ draw a picture of a common example from each. (or cut out of a magazine). You will be graded on how accurate your information is as well as neatness." Sponges (Porifera): Poriferans don’t have mouths; instead‚ they have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter nutrients from the water as the water is carried through the body
Premium Animal Cnidaria Annelid
Phylum Annelida L. annelleus = little ring Annelida have bodies consisting of many essentially similar ringlike segments (somites or metameres).This segmentation usually shows in both external and internal features‚ including muscles‚ nerves‚ and circulatory‚ excretory and reproductive organs. Phylum Annelida This phylum is divided into three classes: Oligochaeta: Earthworms - Most earthworms and their equals are inhabitants of damp soil and fresh waters. Hirudinea: Leeches - The leeches

Stinson‚ Margie Biology 210 Lab Questions: Phylum Annelida You will learn the answers to most of these questions in class and in lab. Great resource: http://www.bumblebee.org/invertebrates/ANNELIDA.htm 1. What does the word annelida mean? 2. Recall‚ some of the nematode worms appeared superficially to have external rings. Describe true segmentation in annelids. How is the true segmentation in annelids differ from having rings around the ectoderm as in nematodes? 3. What two layers

Identify the parts of a sponge (including the spongocoel‚ porocyte‚ epidermis‚ choanocyte‚ mesohyl‚ amoebocyte‚ osculum‚ and spicule) and describe the function of each. a. Lifestyle: sessile‚ immobile filter feeders b. Water circulation i. Epidermis seals outside ii. Flagellated choanocytes lining
